BACKGROUND OF THE INVENTION

This section is intended to introduce various aspects of the art, whichmay be associated with exemplary embodiments of the present disclosure.This discussion is believed to assist in providing a framework tofacilitate a better understanding of particular aspects of the presentdisclosure. Accordingly, it should be understood that this sectionshould be read in this light, and not necessarily as admissions of priorart.

Fuels and other oil products or refined products oftentimes includeharmful chemicals or a physical attribute that should be controlled.Therefore, these products are treated with chemical additives to changethe chemical or physical characteristics of the product. For example,hydrogen sulfide (H₂S) naturally occurs in crude oil. H₂S also hasdetrimental effects on production equipment, as it is highly corrosiveand can degrade process and storage infrastructure, leading to costlyrepairs. There are many safety hazards associated with H₂S. Therefore,it is important to effectively control the hydrogen sulfide within anyvolume of crude oil.

To control the H₂S within large quantities of oil, an additive chemicalor chemical additive may be added to the crude oil to scavenge the H₂Sand render it harmless. This is typically done subsequent to thetransfer of oil from one storage area to another storage area, such asfrom storage tank to vessel, vessel to storage tank, or storage tank tostorage tank, as the transfer creates a volumetric mixing or agitationof the crude oil, which helps in the distribution of the additivechemical throughout the volume of the crude oil. The chemical additive,such as monoethanoloamine (MEA) and monomethylamine (MMA) triazine issimply mixed with the large quantities of crude oil after the crude oilhas been transfer from one oil receiving storage area to another. Thisis a batch type treatment of the crude oil volume. However, because ofthe dangers related to the H₂S, the amount of chemical additive added tothe volume of crude oil is vastly greater than necessary to scavenge theH₂S from the crude oil. This ensures that all the H₂S is processed orscavenged from the crude oil. Typically, the overage amount of chemicaladditive is approximately 40%, i.e., 40% more scavenging chemicaladditive is added to the oil to ensures that all the H₂S is processed.This vast overage of a chemical additive is inefficient and creates anunnecessarily high expense in processing the oil.

Accordingly, a need exists for a system and method of processing arefined products, fuels, or oil in a more efficient manner. It is to theprovision of such therefore that the present invention is primarilydirected.

DESCRIPTION OF SELECTED SPECIFIC EMBODIMENTS

With reference next to the drawings, there is a shown a real time fueladditive processing system for continuously treating flowing crude oil,refined fuel products, or fuel products, reference hereinafter simply asa fuel additive processing system 10, embodying principles of theinvention in a preferred form. The fuel additive processing system 10may be used for the treatment of crude oil, diesel oil, gasoline,refined products, fuel, or other fuel products, which are referencedherein collectively as “fuel”. The fuel additive processing system 10 iscoupled to a conventional fuel transport line 12 that transfers largequantities of liquid fuel from one storage vessel or tank A to anotherstorage vessel or tank B. These fuel transport lines 12 typicallytransfer 12,000 to 15,000 barrels of liquid per hour and have aninternal pressure of 30 to 50 p.s.i. The storage tanks A and B may beland based storage tanks, liquid tanker trucks, liquid tanker ships, orany other large liquid container.

The fuel additive processing system 10 includes a fuel additive storagetank 14 in fluid communication with a liquid conduit or line 16 throughan/off valve 18. The storage tank 14 can contain a large volume of aliquid fuel additive FA, such as 10,000 gallons. The storage tank 14 hasa temperature sensor/transmitter 22, a fill line outlet valve 24, and anadditive level transmitter 26. The additive level transmitter 26 may bea EchoTouch US06 made by Flowline of Los Alamitos, Calif. Thetemperature sensor/transmitter 22 measures the temperature of the liquidcontained within the storage tank 14. A manual flow indicator 28, in theform of a calibration column, is coupled to the liquid conduit 16 tomeasure the flow rate through the liquid conduit 16. A drain valve 30 isalso coupled to the liquid conduit 16.

An additive liquid pump 34 is coupled to the liquid conduit 16 to flowthe fuel through the liquid conduit 16. The liquid pump 34 may be aNeptune 535-S-N3-FA-100737-T-EC500, which has a capacity of 18 GPH, aDP/DT of 100 PSI (250 PSI max) with a ⅓ HP motor at 1,750 RPM made byNeptune Chemical Pump Co., Inc. of Lansdale, Pa. The liquid pump 34 isactuated through a speed/stroke controller 36 that is regulated throughthe electric current passing to the speed/stroke controller 36. Thespeed/stroke controller 36 may be a model number Neptune EC5000 made byNeptune Chemical Pump Co., Inc. of Lansdale, Pa. The liquid pump 34 andspeed/stroke controller 36 are shown as separate items, however, theliquid pump 34 may include a speed/stroke controller 36 as a singleunit. A pressure safety valve 38 is also coupled to the liquid conduit16 so that a portion of the liquid passing through the liquid conduit 16may pass back to the storage tank 14 should a threshold liquid highpressure be reached. A pressure gauge or indicator 40 is coupled to theliquid conduit 16 to indicate internal fluid pressure. The pressuregauge 40 may be a model number PN7692 made by IFM Efector, Inc. ofMalvern, Pa. A flow transmitter 42 that determines the flow rate of thefuel additive through the liquid conduit 16 is coupled to the liquidconduit 16. The flow transmitter 42 may be a model number JVS-12KG/RT-30made by AW Lake of Oak Creek, Wis. A check valve 44 is coupled to theliquid conduit 16 adjacent to an end of the liquid conduit 16 having afuel additive injection nozzle 46 at a junction of the liquid conduit 16and the fuel transport line 12.

The fuel additive processing system 10 also includes a flow ratetransmitter 50 and a chemical or physical property analyzer 52 coupledto the fuel transport line 12 downstream of the additive injectionnozzle 46. The flow rate transmitter 50 transmits the liquid flow rateof the fuel passing through the fuel transport line 12. The flow ratetransmitter may be a model Fluxus F808 made by Flexim GmbH of Berlin,Germany. Lastly, the fuel additive processing system 10 includes a flowcontroller 54 that communicates with the liquid pump speed/strokecontroller 36, flow rate transmitter 50 and chemical or physicalproperty analyzer 52. The flow controller 54 includes a processor,software, and memory. The flow controller 54 may be a model numberCompactLogix 1769-L30ERM sold by Allen-Bradley of Rockwell Automation,Inc. All electronic communications to the flow controller 54 may be donewirelessly or through hard wires.

The fuel additive processing system 10 may be mounted on a skid 60, orother movably platform, to enable the fuel additive processing system 10to be moved from one location to another location.

In use, the fuel additive storage tank 14 is filled or partially filledwith a chemical fuel additive FA to be added to a select flowing fuel oroil supply through the fuel transport line 12 for the treatment thereof.For example, for the treatment of crude oil, the fuel additive may bemonoethanoloamine (MEA) and/or monomethylamine (MMA) triazine that isutilized to scavenge the dangerous target chemical of hydrogen sulfideH2S from the crude oil. However, the present system may be used for anyrefined product, fuel or oil and is not limited to the examples providedherein. The fuel additive may also be a lubricity additive such asSR2009 made by Dorf Ketal Chemicals LLC of Houston, Tex., an antistaticagent or conductivity improver such as SR1795 made by Dorf KetalChemicals LLC of Houston, Tex., a cold flow improver such as SR1690 madeby Dorf Ketal Chemicals LLC of Houston, Tex., or other chemical additiveintended to refine, treat or otherwise process a fuel or oil product.

With the commencement of the flow of a fuel product through the fueltransport line 12, the fuel additive processing system 10 commences itsoperation. As the fuel flows through the fuel transport line 12 the flowtransmitter 50 continually senses the flow and determines the fuel'sflow rate. The chemical or physical property analyzer 52 continuallymonitors the level of a target chemical or physical property within thefuel transport line 12. An example of a physical property that may bemonitored is the conductivity of diesel oil, wherein the diesel oil istreated to have a conductivity within a select range. An example of amonitored chemical may be hydrogen sulfide (H2S) within crude oil withinthe fuel transport line 12. As such, with the transportation of crudeoil through the fuel transport line 12, the chemical or physicalproperty analyzer 52 is an analyzer which senses the level a hydrogensulfide (H₂S) for treatment or scavenging by an additive chemical (fueladditive FA), such as monoethanoloamine (MEA) and monomethylamine (MMA)triazine. For this example, the chemical or physical property analyzer52 may be a model number OMA-300 made by Applied Analytics, Inc orBurlington, Mass. The flow rate sensed or determined by the flowtransmitter 50 and target chemical (H2S) level sensed or determined bythe chemical or physical property analyzer 52 is electronically sent tothe flow controller 54. The flow controller 54 then continuouslydetermines the amount of fuel additive FA to inject into the fuelflowing through the fuel transport line 12.

Should the flow controller 54 determine that the level of a targetchemical is above an acceptable level or acceptable range of level (toohigh), and therefore the amount of the full additive FA treatmentchemical injected into the fuel is inadequate, the flow controller 54immediately increases the flow rate of the treating fuel additive FAtreatment chemical entering the fuel transport line 12 through nozzle 46to compensate for the sensed elevated level of target chemical. Theincrease in the amount of treatment fuel additive FA is accomplished bythe flow controller 54 sending a signal to the speed/stroke controller36, which in turn controls an increase in the speed or stroke of theliquid pump 34 to increase the flow rate of the fuel additive FA beinginjected into the fuel within the fuel transport line 12. The increasein speed/stroke of the liquid pump 34 causes more, or a greater rate of,fuel additive FA treatment chemical to flow from the fuel additivestorage tank 14, through liquid conduit 16, and through additiveinjection nozzle 46 into the fuel flowing through the fuel transportline 12.

Should the flow controller 54 determine that the level of a targetchemical is below an acceptable level or acceptable range of levels (toolow), and therefore the amount of the full additive FA treatmentchemical injected into the fuel is too much and wasteful, the flowcontroller 54 immediately decreases the flow rate of the treating fueladditive FA treatment chemical entering the fuel transport line 12through nozzle 46 to compensate for the sensed reduced level of targetchemical. The reduction in the amount of treatment fuel additive FA isaccomplished by the flow controller 54 sending a signal to thespeed/stroke controller 36, which in turn controls a decrease in thespeed or stroke of the liquid pump 34 to decrease the flow rate of thefuel additive FA being injected into the fuel within the fuel transportline 12. The decrease in speed/stroke of the liquid pump 34 causes less,or a smaller rate of, fuel additive FA treatment chemical to flow fromthe fuel additive storage tank 14, through liquid conduit 16, andthrough additive injection nozzle 46 into the fuel flowing through thefuel transport line 12.

During the fuel processing procedure, the fuel additive processingsystem 10 is manually monitored in ensure the proper working order ofthe fuel additive processing system 10. Additionally, the additivechemical level is electronically monitored through the level transmitter26, the additive chemical temperature is monitored through thetemperature sensor/transmitter 22.

The fuel additive flowing through the fuel additive processing system 10is also monitored at the manual flow indicator 28 prior to the liquidpump 34 and through the pressure gauge 40 subsequent to the liquid pump34. The flow through the liquid conduit 16 also transmitted from flowtransmitter 42.

The system also includes components to ensure the safety and operationof the system. The on/off valve 18 may be closed to prevent the flow ofchemical additive from the fuel additive storage tank 14. The safetyvalve 38 conveys fluid from the liquid conduit 16 back to the fueladditive storage tank 14 should a high threshold pressure within theliquid conduit 16 be reached. Also, the check valve 44 prevents thebackflow of fluids from the fuel transport line 12 into the fueladditive processing system 10.

The following is a more detailed example of the fuel additive processingsystem 10 operation in reference to the treatment of crude oil.

An outgoing volume of crude oil cargo has been found to contain 100parts per million (ppm) of H2S. This amount of H2S should be reducedbelow 10 ppm for safe barge loading and transport. The fuel additive FAis a H2S scavenger that consumes H2S at a ratio of two parts H2S to 1part additive with minimal reaction time and the system's analyzerreturns results instantly.

Initially, a desired injection concentration of fuel additive FA may be50 ppm into the flow controller 54 (specifically the flow control's HMI(human-machine interface), which can be local, remote via cloud, orboth). The flow controller 54 is programmed to take user input ofconcentration and instrument inputs of fuel cargo flow and H2S andcalculate an output signal that will control the liquid pump 34 toinject 0-80 GPH such that the crude oil is loaded at tanker B at between1 ppm to 10 ppm H2S.

The flow rate transmitter 50 transmits the crude oil flow rate throughthe fuel transport line 12 to the flow controller 54. The flowcontroller then sends a control signal to the speed/stroke controller36, adjusting the pump rate proportionally to maintain a 50 ppminjection rate. As the load rate increased to its maximum of 10,000BBL/HR, the crude oil (fuel) and fuel additive FA rates changes from 0,5,000 and 10,000 BBL/HR and 0, 10.5 and 21 GPH, respectively.

Simultaneously, the (H2S) chemical or physical property analyzer 52sends the sensed H2S data from the crude oil stream within the fueltransport line 12 to the flow controller 54. In the event that the cargoexceeds the acceptable limit of 10 ppm, the flow controller 54recalculates the injection rate with the excess H2S as an addition tothe initial input of 50 ppm. If the chemical or physical propertyanalyzer 52 detects 25 ppm of the target chemical H2S while loading at10,000 BBL/HR, the flow controller 54 initiates the new target ppm as62.5 and adjust the injection rate to 26.25 GPH through operation of thespeed/stroke controller 36 and liquid pump 34. In the event thatanalyzer 52 detects 0 ppm H2S, an excessive wasteful amount of additivemight be injected. In order to prevent this waste, the flow controllerhas been programmed to gradually decrease additive rate when theanalyzer detects 0 ppm. In this example of 10,000 BBL/HR load rate, each0 ppm result would direct the controller to reduce additive injectionrate by 5 ppm, or 2.1 GPH. To obtain useful feedback from the analyzer,the loop must factor in the time required for rate changes made at theinjection point to take effect and be observed by the analyzer.Parameters of interest include cargo line displacement between injectionpoint and analyzer, analyzer speed, cargo transfer rate, and additivereaction rate. In this example we assume that the additive reactsinstantly and that the displacement between injection point and analyzeris 500 BBLs. At 10,000 BBL/HR transfer rate, the flow controller wouldrecalculate injection rate based on analyzer input every 3 minutes. Asthe transfer rate changes, the flow controller would recalculate itsanalysis window proportionally to transfer rate. If the analyzerprovides results in the range of 1-10 ppm, no adjustment is made to theadditive rate save for injecting proportionally to the cargo transferrate.

The inputs are continuously monitored by the flow controller 54 tocreate a 0-100% signal to the stroke controller 36 with thisrelationship:

${\frac{\frac{\left\lbrack {{{Manual}\mspace{14mu}{ppm}\mspace{14mu}{Input}} + {{Analyzer}\mspace{14mu}{ppm}\mspace{14mu}{Input}}} \right\rbrack}{2}}{\text{1,000,000}}*{Cargo}\mspace{14mu}{Rate}\mspace{14mu}\left( \frac{BBL}{HR} \right)*\frac{42\left( \frac{GAL}{BBL} \right)}{80}*100\%} = {80\mspace{14mu}{GPH}\mspace{14mu}{Injection}\mspace{14mu}{Pump}\mspace{14mu}{Stroke}\mspace{14mu}{{Setting}.}}$Where the Analyzer PPM Input (API) is determined via a scripted loopduplicating the following instructions:

1. Set API=0

2. If H2S detected is greater than 0 ppm, set Loop Count to 0.

3. If H2S detected is greater than or equal to 10 ppm, API is H2Sdetected.

4. If H2S detected is 0 ppm, increase Loop Count by 1.

5. If H2S detected is 0 ppm, API is −5*(Loop Count).

6. Set Analysis Window equal to Cargo Transfer Rate (BBL/min)/500 BBL

7. Repeat loop in number of minutes equal to Analysis Window.

With the present fuel additive processing system 10 the additivechemical or fuel additive FA is continuously added into the flowing fuelthrough fuel transport line 12 in real-time. This provides for athorough mixing of the additive chemical into the fuel prior to enteringthe storage tank for a much better treatment of the fuel, as opposed tothe prior art batch type processing wherein the additive chemical isadded to a vast amount of stagnant fuel in a storage tank after itstransportation from one tank to another tank, which may cause an unevenmixing of the additive chemical and fuel resulting in a potentiallyhazardous untreated amount of fuel to exist within the storage tank.This uneven mixing must be compensated by the adding of a greatoverabundance of additive chemical or fuel additive FA to ensurethorough treatment of the fuel.

Another significant advantage of the present fuel additive processingsystem 10 is that by continuously analyzing and determining of thetarget chemical and the adding of the additive chemical to the flowingfuel in real-time the overabundance of additive chemical is reduced fromapproximately 40% associated with batch type processing to only 10 to15%. This real-time processing greatly reduces the requirement for theadditive chemical and the costs associated with such. It should beunderstood that as used herein, the term “continuously” is intended tomean that the analyzing, determining, and adding (injecting) is donethroughout the transportation process of the fuel from one storage tankto another storage tank, and that the term “continuously” does not meanthat such actions are being done without interruption, as the term alsoincludes a short periodic analyzing, determining or adding, for example,every 5 minutes.

It should be understood that a set increase in the additive flow ratemay be calculated for a select chemical additive. For example, theincrease or decrease in the additive flow rate may be determined toincremental increase or decrease the volume of fuel additive by 5 ppm.This amount may vary depending on the select fuel additive and selectfuel being treated.

Accordingly, it is seen that a need remains for a fuel additiveprocessing system that processes additive chemicals into the fuel in anefficient manner. It is to the provision of such therefore that thepresent invention is primarily directed.
